Dr Sohei Satoi and colleagues compared multidetector row computed tomography (CT) with other imaging techniques.
The other imaging techniques included computed tomography-assisted hepatic arteriography, and computed tomography during arterial portography.
Further techniques included angiography, and contrast-enhanced computed tomography.
The investigative team assessed the techniques for accuracy in the detection of liver metastasis and vascular involvement of the tumor.
The team evaluated 43 patients with pancreatic cancer from 2002 to 2003.
These patients underwent preoperative evaluation by angiography, and computed tomography-assisted hepatic arteriography.
|Positive predictive values of liver metastasis were superior using multidetector row CT|
The patients also underwent computed tomography during arterial portography contrast-enhanced, and by multidetector row computed tomography.
The team noticed that the sensitivity, specificity of liver metastasis diagnosis were superior using multidetector row computed tomography.
The positive and negative predictive values of liver metastasis diagnosis were superior using multidetector row computed tomography.
The diagnostic accuracy of liver metastasis with tumors less than 10 mm in diameter was superior with multidetector row computed tomography.
The team noted that the surgical and pathological findings of vascular involvement were more accurately diagnosed by multidetector row computed tomography.
The investigators found that multidetector row computed tomography findings were generally similar to surgical findings of vascular involvement.
The investigators observed that multidetector row computed tomography overestimated the incidence of pathological vascular involvement.
Dr Satoi's team concluded, “Multidetector row computed tomography imaging can potentially offer more accurate staging of pancreatic cancer.”
“It may be useful to surgeons both in preoperative planning and for intraoperative guidance.”
